Hi, I've got a pre Intel 1.9 GHz PowerPC G5 & as with many of these iMacs, it has started to have vertical lines appear at random places across the display (just out of warrantee of course!). Apple say it will cost about £450 to get it fixed so I am thinking I could just get a new display & connect it as this would be more cost effective (the Credit Crunch strikes again!). Will any display be compatible & what lead do I need to get? Also, I read somewhere that a second display would only mirror the original. Is it possible to make it an extended desktop on my particular iMac & how do I go about it? Any advice on this would be welcome as I am getting fed up with seeing a stripy screen! Many thanks
